I probably knew less than half of the songs, and if I knew a quarter of the games better than "in passing" (like I know PSIV, while I know of FFVI, but never played it long enough to become even passingly familiar with it) I'd be doing real well.

From my POV, all it really tested was my preconceived notions on what kind of music certain games mighe have had based on what very little I know about their genres.

Also, I agree with Satson. It was hard to distinguish the melody from the rhythm on some of those shitty MIDI renderings.
